The medical literature describes very few cases of bilateral femoral neck stress fractures in healthy adolescents. We studied the case of a healthy adolescent male Marine who suffered severe bilateral femoral neck stress fractures within a span of 7 months. As his level of exercise was no different than his other colleagues, his case was closely scrutinized using biochemical studies, bone specimens, and activity modification over the course of several months. Laboratory studies and observation yielded unremarkable findings, and he went on to return to full training regimens for combat deployments. Thus, even in young healthy males, this type of injury can occur without bony pathology; furthermore, an aggressive surgical approach can result in an optimal outcome.
